The increasing demands of efficiency and effectiveness in the public sector encourage political leaders and policy makers to adopt and apply advanced techniques and solutions to overcome flaws in public organizational performance. Entrepreneurship was introduced in several Western countries as a way to improve their processes and management through adopting private sector management principles and market-oriented techniques. In 2015, Saudi Arabia announced its 2030 vision, which introduced hundreds of innovative and creative initiatives aiming to overcome issues of the turbulent environment, future oil depletion, budgetary pressures, and public demands for efficiency and effectiveness. Building on interdisciplinary perspectives, this study investigates entrepreneurial orientation among Saudi public employees from all administrative regions across the country. Building on McClelland's theory of motivation, this study hypothesizes that the motives of need for achievement, need for affiliation, and need for power are positively associated with entrepreneurial behavior. It also hypothesizes that excessive organizational hierarchy, formalization, and lack of autonomy constrain employees' entrepreneurial activities. Moreover, this study adopts a sociological perspective in proposing solutions for facilitating entrepreneurial orientation among public employees by hypothesizing that human and social capital promote an entrepreneurial orientation. Multiple regression analysis reveals that Saudi public employees with a higher level of need …

Although wireless sensor networks have been successfully used for environmental monitoring, one of the major challenges that this technology has been facing is supplying continuous and reliable electrical power during long-term field deployment. Batteries require repetitive visits to the deployment site to replace them once discharged; admittedly, they can be recharged from solar panels, but this only works in open areas where solar radiation is unrestricted. This dissertation introduces a novel approach to design and implement a reliable efficient solar energy harvester to continuously, and autonomously, provide power to wireless sensor nodes for long-term applications. The system uses supercapacitors charged by a solar panel and is designed to reduce power consumption to very low levels. Field tests were conducted for more than a year of continuous operation and under a variety of conditions, including areas under dense foliage. The resulting long-term field data demonstrates the feasibility and sustainability of the harvester system for challenging applications. In addition, we analyzed solar radiation data and supercapacitor charging behavior and showed that the harvester system can operate battery free, running on the power provided by supercapacitors. A battery is included only for backup in case the supercapacitor storage fails. The proposed approach provides …

In recent years, the sport of women's ice hockey is growing fast worldwide. Upon winning the bid to host the 2022 Winter Olympics, women's ice hockey in China started to develop rapidly. However, the development of women's ice hockey in China has encountered numerous challenges. These challenges include addressing traditional Chinese culture, gender norms, and the process of sport reform. This study used a qualitative case study methodology to examine the perspectives of Chinese women ice hockey players, coaches, club administrators, government administrators, and the parents of youth hockey players to understand how women's ice hockey navigated itself within the institutional complexity to gain legitimacy, and how the different institutional logics impacted the identities of organizations within women's ice hockey in China. An abductive grounded theory approach was used to analyze the transcriptions and archived documents. Findings indicated that there were challenges for the development of women's ice hockey in China at macro level, meso level, and micro level. Actors such as hockey administrations, professional clubs, and ice hockey coaches and players at different levels adopted multiple forms of institutional work to find out ways to incorporate institutional structures that mitigated the fact that there were multiple logics. In addition, …

The purpose of this qualitative, multiple case study was to explore the practices and behaviors of successful Latin@ principals in high-need Texas middle schools focusing on the following three areas: learning, leadership, and context. Varying qualities of leadership essential for leading high-need middle schools coupled with contextual factors such as policy and community were examined. More importantly, this research sought how successful Latin@ leaders promoted a culture of learning in high-need middle schools with a focus on English learners (ELs). High-need schools are defined as those presenting a context that challenges the success of students. The study on leadership in high-need schools focuses on an investigation of strategies principals in these schools may employ and determining ways in which high-need school leaders are prepared and supported. Factors affecting the condition in high-need schools may include: (a) student and community characteristics (e.g., ethnic minorities, mobility, poverty, non-native language speakers), (b) student performance (e.g., math and reading scores, graduation rates, attendance), and (c) other factors (e.g., teacher and leader turnover, staff morale, student engagement). The context of schools matters and effective leaders in high-need schools must be able to lead using contextually appropriate responses. Two Latina principals serving in high-need middle schools, …

This study shows that Arabidopsis thaliana WRKY45 gene has an important role in limiting green peach aphid (GPA; Myzus persicae Sülzer) infestation. WRKY45 belongs to the WRKY family of transcription factors, which is one of the largest transcription factor family in plants. In response to GPA infestation, expression of WRKY45 was systemically upregulated in leaves and roots, with highest expression in the vascular tissues, which are the site of aphid feeding. GPA colonization was better on the wrky45 mutant compared to the wild-type (WT) plant. In contrast, GPA poorly colonized plants that were overexpressing (OE) WRKY45, thus confirming an important role for WRKY45 in plant defense to the GPA. A WRKY45-dependent process adversely impacted the reproductive rate of GPA and feeding from the sieve elements. RNA-seq experiments indicated a major impact of WRKY45 overexpression on expression of genes associated with dehydration and abscisic acid biosynthesis and signaling. In agreement with the RNA-seq data, ABA content was also higher in WRKY45-OE plants. However, genetic studies with an ABA-insensitive mutant (abi2-2) indicates that the WRKY45-OE conferred resistance to GPA is mediated through an ABA-independent mechanism. WRKY45-OE plants showed enhanced tolerance to drought and salt stresses. Genetic studies indicate that ABA signaling is …

During the Great Depression, for the first time in its history, the federal government provided relief to the unemployed and destitute through myriad New Deal agencies. This dissertation examines how "general relief" (direct or "make-work") from federal programs—primarily the Emergency Relief and Construction Act (ERCA) and Federal Emergency Relief Administration (FERA)—was acquired and administered by the government of Texas through state administrative agencies. These agencies included the Chambers of Commerce (1932-1933), Unofficial Texas Relief Commission (1933), Texas Rehabilitation and Relief Commission (1933), Official Texas Relief Commission (1933-1934), Texas Relief Commission Division of the State Board of Control (1934), and the Department of Public Welfare (1939). Overall, the effective administration of general relief in the Lone Star State was undermined by a political ideology that persisted from, and was embodied by, the "Redeemer" Constitution of 1876.

A considerable amount of research has been done surrounding education in classrooms from kindergarten to Grade 12, but little research has been done surrounding early childhood education (ECE) beginning with birth to age 4. As a result, research is needed that examines interventions aimed to improve the quality of early childhood education for young bilingual learners at the earliest stages of schooling. The present study examines current efforts to serve the specific population of young bilingual children entering classrooms in an urban school district in North Texas. The focus of this study includes the access and examination of quality ECE programs (defined by the extent to which bilingual children have access to bilingual education programming). The present study also observes the visibility of young bilingual children who receive services that are responsive to their characteristics, experiences, and specific needs. Lastly, this study used a multiple regression analysis to examine the Kindergarten Early Assessment test that has been put in place to measure the school readiness performance of bilingual children in this urban district. Specifically, the analysis included program type, language of assessment, socio-economic status and gender variables.

The purpose of this transcendental phenomenological inquiry was to explore college-aged women's experiences of body positivity and self-acceptance. I applied a conceptual framework that blended feminist identity development model (FIDM) and relational cultural theory (RCT) to answer the following questions: (a) what are the lived experiences of college-aged women who identify as having a positive and accepting body image? and (b) how do college-aged women's intersecting identities contribute to the development of positive and accepting body image? Ten college-age women participated in the current study. The participants provided detailed accounts of their experiences of body image throughout their life. Five overarching themes were identified through data analysis of the interview transcripts: (a) advocating for self and others, (b) beauty expectations and societal definitions, (c) intersecting identities, (d) journey of acceptance, and (e) relationships and community. Participants offered insight into the development of their current position of body positivity and self-acceptance that serve as implications for other relevant contexts. Implications and recommendations drawn from the participants' experiences can inform preventative and treatment care in educational settings, family environments, clinical practice, and integrated care.

This dissertation is an examination of the interactions of enslaved body servants with their Texas Confederate masters from the American Civil War through the early twentieth century. The seven chapters of this study follows the story of these individuals from the fires of the Civil War, through the turbulence of Reconstruction in Texas, the codification of "Lost Cause" memory in the American South, and the exploitation of that memory by both former body servants and their ex-Confederate counterparts. This study demonstrates that the primary experience of blacks in the Confederate service was not as soldiers, but as enslaved laborers and body servants. Body servants, or camp slaves, were physically and in some cases emotionally close to their enslavers in this war-time environment and played an important part in Confederate logistics and camp life. As freed peoples after the war, former body servants found ways to use the bonds forged during the war and the flawed ideas of Lost Cause memory as a means to navigate the brutal realities of life in post-Civil War Texas. By manipulating white conceptions of former body servants as "black Confederates," some African Americans effectively "passed as gray," an act that earned money, social recognition, and …

Rome was among the largest cities in Europe during the Republic era, with a population that was diverse in social status and ethnicity. To maintain public order and social control of such a large, continually growing and shifting population that encompassed mixed cultures and Roman citizens, the Roman elites had to use various methods to keep the peace and maintain social stability. As religion was so deeply ingrained into every aspect of Roman life, it is worth taking a deeper look into how those in charge used it to maintain peace and relative control in Rome and its territories. Chapter 1 offers a brief look at the history of Roman religion, its terms and definitions, and the idea of social control as it pertains to this thesis. Chapter 2 shows the motivations of the Roman elite classes in their use of religion to maintain public order and enforce social control of the mass population. Couched in the need to uphold the Pax Deorum or Peace of the Gods, religious piety and order was cultivated as a means to protect the Republic from harm. Chapter 3 explains how the Patrician and Plebeian classes directed the attention of the residents of Rome …

In this research work, an innovative method for measurement of thermal conductivity of a small volume of liquids, microsphere, and the single cancer cell is demonstrated using a micro-pipette thermal sensor (MPTS). The method is based on laser point heating thermometry (LPHT) and transient heat transfer. When a single pulse of a laser beam heats the sensor tip which is in contact with the surrounding liquids or microsphere/cells, the temperature change in the sensor is reliant on the thermal properties of the surrounding sample. We developed a model for numerical analysis of the temperature change using the finite element method (FEM) in COMSOL. Then we used MATLAB to fit the simulation result with experiment data by multi-parameter fitting technique to determine the thermal conductivity. To verify the accuracy in the measurement of the thermal conductivity by the MPTS method, a 10µl sample of de-ionized (DI) water, 50%, and 70% propylene glycol solution were measured with deviation less than 2% from reported data. Also, to demonstrate that the method can be employed to measure microparticles and a single spherical cell, we measured the thermal conductivity of poly-ethylene microspheres with a deviation of less than 1% from published data. We estimated the …

Depression in childhood is a significant mental health concern, impacting cognitive, affective, social, behavioral, and physical domains. Children who experience depressive symptoms are at an increased risk for physical and mental health, social, and behavioral problems throughout adulthood. Children who are marginalized due to their socioeconomic status, racial and ethnic identities are at an increased risk to experience depression and limited access to mental health care. Further, previous research has demonstrated limited efficacy of depression treatments for young children. In this study, I examined the efficacy of child-centered play therapy [CCPT], a culturally and developmentally responsive treatment, on depression among young children. Participants were 71 children from five Title 1 elementary schools in the southwestern U.S. referred by school personnel for depressive symptoms (49 males, 22 females; ages 5-9, mean age M = 6.21). The sample consisted of 14 (19.7%) African American, 3 (4.2%) Asian American, 15 (21.1%) biracial, 19 (26.8%) Caucasian, and 20 (28.2%) Latino children. Participants were randomly assigned to eight weeks of twice-weekly CCPT treatment group (n = 34) or a waitlist control group (n = 37). Results of doubly multivariate repeated-measures MANOVA revealed statistically significant improvement in depressive symptoms for children who participated in CCPT on …

Virginia Axline developed a new field of child psychotherapy by applying a nondirective approach to the burgeoning experimentation of utilizing play in therapeutic work with children. While much biographical information is available regarding other leaders in the fields of counseling and psychology, historical research into Axline and her development of child-centered play therapy represent a gap in the literature. The purpose of the current study was to: 1) examine the professional contributions of Virginia Axline; 2) gather personal information regarding Axline that contributes to deeper understanding of her theory; and 3) identify life circumstances or events that influenced Axline's professional contributions. Historical methodology was utilized to locate and examine artifacts and materials necessary to create an interpretive biography of Axline's life and work, with a focus on her professional influences, experiences, and contributions. Historical methods utilized include historiography, oral history, and interpretive biography, with an emphasis on established and accepted source criticism and data synthesis processes. The research yielded a number of historically significant and previously unknown documents valuable to the field of CCPT including personal correspondence, academic writings, and interviews, as well as academic and government records. The research also established new information about and understandings of several of …

Childhood poverty is a prevalent concern in the United States and is associated with poor psychological and academic outcomes. Psychosocial stressors associated with life in poverty may interrupt the development of a positive self-concept, ultimately hampering the academic achievement of children in poverty. As the therapeutic objectives of child-centered play therapy (CCPT) support the development of an increasingly positive self-concept, I explored the impact of CCPT on the academic achievement of children in poverty. Participants were composed of 55 students between the ages of 4-7 years old from seven Title 1 elementary schools in the southern United States. Of the 55 study participants, 12 (22%) were female and 43 (78%) were male. Regarding participant ethnicity, 7 (13%) were African American, 1 (2%) was Asian American, 5 (9%) were multi-racial, 35 (64%) were Latino, 6 (11%) were Caucasian, and 1 (2%) did not report ethnicity. Participants were randomly assigned to either a 16 session CCPT treatment group (n = 25) or a waitlist control group (n = 30). A mixed between-within ANOVA was conducted to evaluate improvement in academic achievement scores between treatment and control groups across time. Results indicated a statistically significant interaction effect on the Early Achievement Composite Score …

Serpent and dragon symbolism are ubiquitous in the art and mythology of premodern cultures around the world. Over the centuries, conflicting hypotheses have been proposed to interpret this symbolism which, while illuminating, have proved insufficient to the task of revealing a singular meaning for the vast majority of examples. In this dissertation I argue that, in what the symbolist Rene Guenon and the historian of religions Mircea Eliade have called ‘traditional' or ‘archaic' societies, the serpent/dragon transculturally symbolizes what I term ‘matter,' a state of being that is constituted by the perception of the physical world as ‘chaotic' in comparison to what traditional peoples believed to be the ‘higher' meta-physical source of the physical world or ‘nature.' What is called ‘nature,' I argue, is also considered in ‘Tradition' to be a perception of, from a certain state of consciousness, that aspect of existence that is called samsara in the Hindu philosophy of Vedanta, which Guenon equivalently describes, from a broadly traditional perspective in The Symbolism of the Cross, as "the indefinite series of cycles of manifestation." ‘Chaos,' according to Eliade in The Sacred and the Profane, is "the amorphous and virtual…everything that has not yet acquired a ‘form.'" The following …

In the last few years, the world has been gripped by a crisis of forced migration and displaced persons. Being forced migrants, asylum-seekers are a unique and diverse population, originating from many countries with different backgrounds and experiences. This makes fulfilling the information needs of the asylum community difficult. Online participatory platforms, such as blogs and discussion forums, are flexible, adaptive information resources that could be used to meet the diverse needs of this population. In this study, I compare two online resources used by asylum-seekers, a blog and discussion forum, using social network analysis and topic modeling techniques. Through these analyses, I have determined the conversational archetype the best reflects both websites and discovered the information needs expressed and, in many cases, resolved through conversations in these online spaces. The core finding of this study is that providing direct access to an expert, such as through an interactive blog, promotes dialogue on a greater variety of topics and increases the likelihood of a thorough response. Furthermore, blog posts may inform participants' comments by providing them with the necessary vocabulary to participate fully in the online setting.

Citation analysis, which provides insights into the influence of particular scholarly work in a field of study, can also show epistemological "turns" through patterns of citations over time. This study explored the impact of postmethod epistemology on the shared knowledge of the English-as-a-second-language (L2) education community over a 26-year period. The approach consisted of tabulating and analyzing citations in 125 articles from two major journals, Teaching English to Speakers of Other Languages Quarterly (TESOL Qrtrly) and English Language Teaching Journal (ELT). The time period covered was 1994, when the term postmethod was introduced in TESOL Qrtrly, through 2019. Attention went to the following questions for each journal and for both journals together: (i) who is the most influential of the three major postmethod authors, B. Kumaravadivelu, Richard Allwright, or Hans Stern? (ii) what was the most cited postmethod publication? and (iii) have there been patterns over time for citations of postmethod authors and publications and for the use of the term postmethod? Of the three postmethod authors, Kumaravadivelu was the most cited in the two journals combined. For TESOL Qrtrly, Kumaravadivelu was the most cited, and Stern was second. For ELT, Kumaravadivelu and Allwright had an equal number of citations, …

Given the growing number of socially conscious and ethical consumers, brands have been taking a strategic approach to corporate social responsibility (CSR) by integrating socially responsible activities into the brand's core value proposition in order to remain relevant in the marketplace and drive brand equity. Extant research on CSR has investigated its effect on various consumer behavior outcomes. However, from a brand-building perspective, there is still a lack of understanding on how to effectively leverage CSR, and not enough directions on how to overcome its challenges in order to build brand equity. Therefore, through three essays, the objective of this dissertation is to provide a deep understanding of the effect that CSR has on brand equity while revealing brand-building strategies that can be implemented to effectively leverage CSR, specifically within the (1) global, (2) luxury, and (3) co-creation contexts.

This dissertation explores the how external threat from militarized interstate disputes and interstate rivalries affect the relationship between the state and the ethnic groups within its borders. Specifically, it finds that national identity, the preservation of ethnic regional autonomy, and the formation of ethnic-based militias are all influenced by states involvement in international conflicts. In Sub Saharan Africa, discriminated groups are less likely to identify with their national identity and when the state is involved in an interstate dispute, while the rest of the country increases their likelihood to identify with the nation, discriminated groups cling to their ethnic identity. During and interstate rivalry, ethnic groups face a heightened risk of the state taking away their autonomy over a region. If the rivalry becomes too intense or the ethnic group shares kin with the rival, the ethnic group has lower chance of losing their autonomy during rivalry. Finally, ethnic minority seeking to form a militia are able to form one faster if their ethnic group is well represented in the military's rank and file or if their co-ethnics in the rank and file had combat experience in an interstate dispute were military force was used. Ethnic groups that are well …

The Magellanic woodpecker (Campephilus magellanicus), the largest woodpecker in Central and South America, is declining throughout its range. Notably, limited research has been conducted on the Campephilus genus, especially for island populations. Mostly during austral summers 2015-2017, I explored the ecological importance and population structure of Magellanic woodpeckers on Navarino Island, Chile (55°04′S, 67°40′W). First, I assessed how coleopteran larval density and distribution within trees may influence Magellanic woodpecker foraging behavior. Second, I designed an experiment to determine which of three detection methods would best elicit a woodpecker detection. Third, I conducted a population genetics study to elucidate trends within and among Magellanic woodpecker populations to better inform management decisions. I identified two coleopteran species: one lucanid (Erichius femoralis) and one cerambycid (Microplophorus magellanicus) within two lenga (Nothofagus pumilio) trees foraged on by Magellanic woodpeckers. Maximum woodpecker excavation depths were 71-90 mm; most larval gallery depths were 51-70 mm. The drumming device most effectively influenced the likelihood of a woodpecker detection. The odds of a woodpecker responding were 2.14 times more likely than responding to either a playback or control. On Navarino Island, I observed a pattern of isolation by distance among sampled woodpeckers, slight female sex-biased dispersal, and family …

A quantitative, causal-comparative study between single gender and traditional mixed gender schools was conducted to examine how single gender schooling affected the academic achievement of African American males in a high-poverty urban community. This study examined the differences in TSI and EOC scores between African American males who attended a single gender male high school and a traditionally mixed gender high school serving students in the same community in Fort Worth, Texas. A two sample t-test was used to compare the STAAR and TSI scores of the two groups of African American males. Microsoft Excel was used to collect the descriptive statistical data and analysis was conducted in SPSS version 25.0 for Windows. A detailed description of the participants, the research design that was used in the study, a description of instruments that was used to analyze the data, research problem, research questions on which the study was based, and a description of data analysis methods that was used. This quantitative research compared the STAAR and TSI scores in language arts, math, and reading. The findings of study indicate the single-gender school model impacts the academic achievement of African American males in a particular community in Fort Worth, Texas. The …

The purpose of this study is to revisit the question of whether welfare benefit levels influence female headship, and whether the effect differs between the two main eras of welfare policy relevant to female headship, Aid to Families with Dependent Children (AFDC) and Temporary Assistance to Needy Families (TANF). This study adds to the existing literature by including more up to date data allowing for a comparison between the AFDC and TANF eras. Results show that the effect of welfare benefits on female headship rates changes from negative to positive after welfare reform occurred among blacks, while no change occured among whites.

The first study project is based on modeling Earth abundant 3d transition-metal methoxide complexes with potentially redox-noninnocent ligands for methane C–H bond activation to form methanol (LnM-OMe + CH4 → LnM–Me + CH3OH). Three types of complex consisting of tridentate pincer terpyridine-like ligands, and different first-row transition metals (M = Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) were modeled to elucidate the reaction mechanism as well as the effect of the metal identity on the thermodynamics and kinetics of a methane activation reaction. The calculations showed that the d electron count of the metal is a more significant factor than the metal's formal charge in controlling the thermodynamics and kinetics of C–H activation. These researches suggest that late 3d-metal methoxide complexes that favor σ-bond metathesis pathways for methane activation will yield lower barriers for C–H activation, and are more profitable catalyst for future studies. Second, subsequently, on the basis of the first project, density functional theory is used to analyze methane C−H activation by neutral and cationic nickel-methoxide complexes. This study identifies strategies to further lower the barriers for methane C−H activation through evaluation of supporting ligand modifications, solvent polarity, overall charge of complex, metal identity and counterion …

The current study focused on dyadic discrepancy, the difference between two individuals. A Monte Carlo simulation was used to compare three dyadic discrepancy estimation methods across a variety of potential research conditions, including variations on intraclass correlation, cluster number, reliability, effect size, and effect size variance. The methods compared were: raw score difference (RSD); empirical Bayes estimate of slope in multilevel modeling (EBD); and structural equation modeling estimate (SEM). Accuracy and reliability of the discrepancy estimate and the accuracy of prediction when using the discrepancy to predict an outcome were examined. The results indicated that RSD and SEM, despite having poor reliability, performed better than EBD when predicting an outcome. The results of this research provide methodological guidance to researchers interested in dyadic discrepancies.
